The corresponding surface of the brain was injected and covered with 

 a similar fluid, in which streptococci were discovered on bacteriological 

 examination. 



Both guttural pouches were inflamed, that of the left side being full 

 of blood-stained offensive pus.

 PSEUDO-CANCROID OF THE LIP. 



25. Four-year-old female cat, brought for examination on the 

 2ist April, 1894. 



Had been ill for a year. On the centre of the free border of the 

 upper lip this cat had shown a little flattened, hard tumour, which 

 afterwards became ulcerated. The wound gradually extended on 

 either side as far as the labial commissures, and above to the nostrils. 



It was of a regular, concave shape. The base exhibited a thin 

 indurated layer. The surface was reddish or greyish in colour, accord- 

 ing to the point chosen. On examining it more clos-ely the red areas 

 were seen to be regular, moveable, and to resemble cicatrices ; whilst 

 the greyish points were formed by little crusts covering shallow depres- 

 sions, apparently caused by extension of the lesion. 



The ulcer was sharply defined, and the skin marginating it covered 

 with hair. Where it joined the mucous membrane there was neither 

 swelling nor induration. The incisor and both canine teeth were 

 exposed. 



On either side of the upper part of the neck were two hard inflamed 

 lymphatic glands the size of large peas. 



A particularly interesting feature was the existence at the base of 

 the dewclaw of each front foot of an ulcerated wound showing the 

 same appearances as that on the upper lip, and only extending to the 

 papillary layer of the skin. The greater portion of the surface was 

 rose-red, though greyish points could be seen similar to those on the 

 ulcer of the lip. The wound on the right paw measured a little more 

 than three quarters of an inch in length, and about three eighths of an 

 inch in width. It was crescent-shaped, and surrounded the paw. That 

 on the left paw was slightly smaller, but situated at exactly the same 

 point. 



These two ulcers occupied the part which cats are in the habit of 

 licking with the tongue when cleaning themselves. They were evi- 

 dently developed by auto-inoculation, in consequence of repeated con- 

 tact between the skin and the labial ulcer. 



The patient was not left in hospital. We prescribed dressing the 

 ulcers with a 20 per cent, solution of iodine. 



The animal was not brought back. 



26. Six-year-old male cat, left in hospital on the 20th May, 1895. 

 Two years before had suffered from an ulcer of the lip. Recovery 



occurred spontaneously after some months. On the 15th April, how- 

 ever, a new ulcer was noted.
